TRENTON — Today, it's the Land of Enchantment. On Friday, the Volunteer State.

Gov. Chris Christie, the chairman of the Republican Governors Association and a potential 2016 presidential candidate, continues his ongoing tour of the U.S. over the next two days.

He's in New Mexico today to support Gov. Susana Martinez's re-election bid. The pair was scheduled to meet with voters at a coffee shop in Roswell this morning.

Christie will also attend three fundraisers for Martinez later in the day, as well as a fundraiser for the RGA, the organization that helps raise money for GOP gubernatorial candidates.

He and Martinez have campaigned for each other in the past. Christie visited New Mexico in 2010 to back Martinez's first bid for governor. She returned the favor last fall with a visit to New Jersey for Christie's re-election campaign.

Christie has been president of the RGA since November and has helped the group raise more than $33 million for various candidates in that time, often traveling across the country to campaign for them. Last week, he was in Florida with Gov. Rick Scott. On Thursday, Iowa Gov. Terry Branstad visited New Jersey for a fundraiser hosted by Christie.

The busy schedule continues Friday, when Christie is scheduled to deliver the keynote speech at the Tennessee Republican party's annual Statesmen's Dinner.

Not everyone is happy with Christie's appearances. One of Iowa's Republican congressman, U.S. Rep. Andy Holt, wrote on his Facebook page that Christie speaking at Friday's dinner was "an absolutely terrible idea."

"Really, Tennessee GOP? Gov. Chris Christie? What an absolutely terrible idea! Why would we want to cloud Tennessee's conservative Republican Party with this questionable political figure?" Holt wrote. "What about having a truly conservative Republican team-player come and speak to us and excite the 'real' base of the Republican Party in Tennessee? I'm willing to make suggestions if necessary."

The Democratic National Committee also released a mock promotional video this morning saying Christie's stops across the country are part of the GOP's 2014 "Summer Scandal Tour."

"Christie and other GOP governors have become bogged down in scandal, while failing to deliver for middle class families — from lagging state economies, to mounting budget crises, to broken promises to create jobs," the DNC said in a statement.

Christie's administration has been plagued for months by allegations that members of his staff and administration closed lanes at the George Washington Bridge last September in a bout of political retribution. The governor has denied any involvement.
